I'm having difficulty getting changes made in "portal.css" recognized on my site in DNN 7.4.1 using the stock "Gravity" skin, and am confused as to the order of precedence of this stylesheet. My understanding is that portal.css is supposed to be the highest precedence, and anything I define in it would override other declarations, but this doesn't seem to be the case. 

As a simple test, I changed the definition of "Body" to be "background-color: red". (Using Admin->Site Settings->Stylesheet Editor).

I then bring up F12 dev tools in Internet Explorer with a site page loaded, to inspect the CSS rules being applied, and what I see is that "skin.css" is taking precedence over "portal.css". I see where my rule has been defined, but it's being overridden by a rule in skin.css. At least that's how I interpret it. The following screen shot shows what I'm referring to:

Could someone help me understand this, if I am interpreting this correctly, and if this is unexpected (a bug?)?

Hi Robert,

CSS specificity is also important. The id "Body" that is in the skin.css is more specific than the element name. Try changing your CSS definition to use "#Body{background-color:red}" and it should override the skin.css. Also, if this is to be a permanent change to the CSS, it is recommended to make your changes to the skin.css, instead of the portal.css as any Admin could go in and remove all of your updated styles.

You have been bitten by specificity. an ID selector trumps an element selector.

Thanks guys. I should have known it was my lack of CSS knowledge rather than a DNN issue. ;-)
